Park, in the county of Cook and State of" Illinois, have invented certain new and use ful Improvements in Automobile-Trailers, of which the followin is a specification.

This invention re ates to trailers to be used with automobiles or other vehicles, and parbe used with one or more automobiles, in order to facilitate loading or unloading goods,` or for other purposes; and the general objects of the invention are toproduce an improved trailer for general use and an improved oombination ofa trailera traction` Specification of Letters Patent. Patented Sept, 16, 1919,.

Application led July 2, 1917. Serial No. 178,168.

rocking bolster` comprising a lower plate 18 and an upper plate 19, and fixed to the upper plate is a frame 20.- Notches 21 are provided in the frame 20, and these notches are adaptl ed to receive the handle bar 15 of the trailer when the trailer is to be moved by the automobile.

When the trailer is to be loaded it is ordinarily separated from the tractor, and the ticularly where a number of trailers are to reach is supported by any suitable means at tween the side stakes. 22and extending to or beyond the handle -15 if desired. The tracf tor is thenbacked underthe reach, and the reach lowered so that the handle 15 passes vehicle, and means for connecting the traile r\. into the notches 21. To hold the lumber Fig. 4.

o illustrate my invention I will considerl it as applied to lumber use; but it may be applied to many other uses equally as well. Inl lumber yards or in factories requiring the use of much lumber, considerable time is required to load and unloadv the lumber from trucks; and to obviate the need of the traetion vehicle, or the tractor, standing idle during a, large portion of the time itis desirable to have trailers whichl may readily be connected or disconnected from the tractor; and which, if desired, may be moved around more or less by hand, especially with light loads. For this purpose I- provide a trailer comprising ordinary supporting -wheels 10, and a frame 11 supported on the aXle 12 of the wheels in any` suitable manner,

such as by springs 13. FlXed to the frame 11, in a manner hereinafter described, is a reach 14 which may be used as a handle for operating manually the trailer.

Any suitable traction means may be used. I prefer for the purpose automobiles or auto trucks, comprising rear wheels 16 supporting a frame-17, which in turn supports a firmly in place and 'to fasten the'reach to the frame 20, straps 23 are fixed to the frame,

y thestraps having rings 24, to which are fastened a chain 25 passing over the lumber. When fastened in this manner the handle 15 cannot beforced upwardlyout of the notches 21. When the trailer is not loaded and it is desired to fasten it to the tractor the chain 25 is fastened to the rings 24 and wrapped around the reach. From this it will be seen that the reach and the handle 15 form a continuation of the `frame 11 lfor supporting the lumber.

With a trailer fastened to vthe tractor as above described it becomes desirable to. arrange vfor a very material amount of flexipose a bolsterl without a king bolt, but 1n- .stead having a pin 26 fixed to the lower plate 18, and passing freely through .an opening- 27 in the plate 19. A project1on'28 fixed to the upper end of the pin 26 prevents the complete vseparation 'of the lates, exc'e t when turnedthrough an ang e of 180 egrees so as to cause the .projection 28 to register with a slot 29 in the upper plate through which the projection maypass. B y

rounding. the outer 'adjacent e ges of the plates, and by having the projection 28 nor- .mallyspaced somewhat from the upper surface ofthe plate 19 a'degree of flexibility is obtained suilicient to allow the tractor and trailer to pass over very material depressions or elevations in the road without injury.

In order -to adapt the trailer to lumber of 'the beams of both frames.

diiierent lengths or for other purposes, I

rovide means for making the reach extens'i- ,le. The rear portion of the reach, comprises a frame consisting of the longitudinal beams and the cross beams 31 rigidly connected. This frame is longitudinally slidably mounted in the frame 11 of the trailer between the cross beams 34 and the floor 35, guided by an angle; iron 36; and relative longitudinal movement of the two frames is prevented by means of pins 32 passing through the floor, the angle iron and A plurality of holes 33 provide means for adjusting the position of the reach frame with reference to the trailer frame so as to shorten or to lengthen the reach as desired.

I claim as my invention:

l. The combination of a tractor, a twowheeled trailer, connecting means comprising a rocking bolster, and means for immovably but detachably connecting the upper member of said bolster to said trailer.

2. The combination of av tractor, a trailer, connecting means comprising 'a rocking bolster, said bolster having a notch in its upper surface, la handle fixed-to said trailer and extending transversely, said handle arranged to be placed in said notch, and adapted to hold lumber, and means for holding said handle in said notch, said latter means at the same time holding said lumber on said handle. y/

3. The combination of a tractor, a twowheeled trailer, a rocking bolster mounted on said tractor, a reach extending forwardly from said trailer, and means for immovably but detachably fastening said reach to the upper member of said bolster.

' 4. The combination of a tractor, and a trailer, and means for connecting said trailer to said tractor; said means comprising an extensible reach fixed to said trailer, and adapted to hold lumber, and means for detachably connecting said lumber to said reach, said means also adapted to detachably .connect said reach to said tractor.
